The cross-flow turbine 120 and the cross-flow volute 130 form a cross-flow duct 100, the turbine 310 and the centrifugal volute 320 form a centrifugal duct 300. A combination of the cross-flow duct 100 and the centrifugal duct 300 forms the cross-flow centrifugal duct configuration of the split-floor-type air conditioner. A portion of the body corresponding the cross-flow duct 100 has a first air inlet frame component 400 used to supply wind to the cross-flow turbine 120 located inside the cross-flow duct 100, and a first air outlet 500 used to outlet wind passing through the cross-flow turbine 120, the body has a second air inlet frame component 600 which can supply wind to the turbine 310 located inside the centrifugal duct 300, the body further has a second air outlet 700 which can outlet wind passing through the centrifugal volute 320.

The cross-flow turbine 120 and the turbine 310 can be driven to rotate simultaneously by the first motor 110, meanwhile two different kinds of gas flow modes are existed in the body with the action of the cross-flow volute 130 and the centrifugal volute 320. Air flow coming from the first air inlet frame component 400 flows in along a direction perpendicular to an axis of the cross-flow turbine 120, that is, the air flow coming from the first air inlet frame component 400 flows in along a radial direction of impeller of the cross-flow turbine 120, passes through an inside of the impeller, and is discharged through another end along the radial direction, the air flow can flow crossly or flow transversely, and be discharged through the first air outlet 500 finally, a route of the air flow is a straight line.
